Essentially, you need 20 years of PhD candidates doing research into the area and trying to isolate the various variables at play. So it will take some time to get to a greater level of certainty here and find a statistically significant impact on social unrest. It would be hubris to say that we can precisely disentangle those factors right now, particularly in Syria, where there’s an ongoing conflict, or in Egypt where there’s a great level of instability. It’s hard to study.
